2018 13'' TB MBP with Vega 64 WQHD?

I would like to ask if somebody knows if my quad core MBP would be able to get 60 fps min at max details in games like gtaV, Witcher 3, Steep or Hitman 2 on a WQHD monitor with a Vega 64 in a Razer Core X?

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.
